Dimensions for Shimano DH-F7 Dynamo Hubs - Intro
I have just spect about 1 hour looking for dimesions for any of the following hubs:
Dimensions for Shimano DH-F7 Dynamo Hubs - Dimensions
Left Flange = 74mm
Right Flange = 74mm
Centre to Left Flange = 19.7mm
Centre to Right Flange = 20.8mm
OLD = 74mm
Edd spoke calculator has dimension logged for the DH-703-SB, but not for the for the DH-702.
If you are build a ETRTO 349 wheel for a Brompton then, many retailers will sell a spoke pack to fit your chosen dynamo.
For a 305 ETRTO wheel, best use the spoke calculator. I calculated 125.7mm spokes based on 28 spokes at 2 cross.
I would have much preferred to use a DH-702 (Capreo Dynohub) as they are cheaper, but you try finding a 24 hole 305 rim!! Not easy. You can't even buy un-drilled rims of that size.
